    I can send you some numbers. It is typically 5-10% throughput increase
    under load. Obviously this work won't help a single task on a single
    user system. But things like (ack!) dbench 16 show a marked
    improvement.

    I have an explanation. We can schedule quicker off a woken task. When
    an event occurs that allows an I/O-blocked task to run, its time-to-run
    is shorter. Same event/response improvement that helps interactivity.
